vTo all whom itmajf/ concern Be it known 4that we, JOHN H. GiLns and DONALD M. Gruss, citizens of ,the United States, residing at Amsterdam* .in 'the county vof Montgomery and; State oi- New York,

have invented lnew and useful lmpr'oveme'iits l" in Dyeing-Machines, of which' the following is a specification.

This invention relatesto machines for the dyeing of yarns and the like and con# sists in a new and durable-construction andv improved arrangement whereby danger from the corroding action vof the dye liquor on the parts is avoided, in this respect overcoming an objectionable' and highly detri-l mental defect -heretofore present in machines oi this character. -To this end wej have v de vised means" for rotating vthe supporting ysticks from whichl the springs heretofore l'commonly employed are eliminated thereby .reducing the liability of `ir'iterrnp'ting the operation andcausing improper dyeing of,

the yarn by reason of broken springs. Such springs are preferably made of steel or bronze, and when' vsubjected to the action of,

certain dyes,A such'as black-.sulfur dye and acid colors,. the corrosion' is'so greattliat .-.catedwith the advancing mechanism for. I rotating 'the sticks,"wh ich `support theskeins itiis. necessary to replace them very, often toinsure'against their breakin and the consequentproduction ofl imper ectly dyed yarn.

The'sticks at their outer ends are' fitted to apertured rings and are'retained in posit-ion by? the arrangement described and shown in ig. 4.`

In Fig. l2 our improved double socketl bearing 1s shown in detail and .has at each side a'squared-socket 22 for the ends of the opposite l'sticks'. Upon the bearing is formed the vratchetl ange 16 to coperate with an escapeme'nt-.dog similar to the arrangement "of FigjQ and likewise at .the opposite 'side there-isarranged the star lwheel 19 to coact with a center trip similar to trip4 t of ,'Fig. 1` and now to be described in connec-l tion withFigs.` 7 and`8.

Our improved trip is shown pivotally supported on pin y4,7 in a bracket 48 secured on the under side of the top 41:1 ofthe ina- .chine.` l It' includes the depending trip arm 50 having-adju'stablysupported at its end an antifriction roller '51 positionedto engage the-fingers'of the star wheels 19 for r1the The sticks are revolved in .the direction' shown by arrow in Fig; 1' andthe depending trip arm 50 has a. lateral arm 54 4carrying an' .adjusting screw to engage a lug 56 oiian upwardly eXtendingarm'57 also pivotally supported on'pin/i7. The arm 57 is held to be normally rigidso' that the roller 51 in the'path ofthe-revolving star wheels to `be enffaged thereby,V ywill'be held rigid through the engagement of screw l55 and lug 56 to rotate the star' wheels a distance determined by the position of the roller4 and down'in its slot. The depending stop arm,50 is free to swing toward the left away from the arm 57 thereby' yielding to permit a reverse revolution ofthesticks for vun-l loading the .yarn Vwithout disturbingthe A counter-balance weight 604 trip device. is provided on the arm 50 normally' to maintain it in its operative position; v.Provision is also made adapting your improved trip to yield in r a forward direction under errcess pressure *as may -be caused by the resistance offered by the star wheels-whenyarn is wound aroundthe stick. To that endf a s ring-65 is connected'to the upper end of die Zarm 57 and toa fixe-d bracket .66.

In Figs. l, -1 1 and 14 there is illustrated ing for the reverse movement of the machine f our improved stick adjusting mechanismop'- erative to 'adjust the distance between the outer Sticks-l0 and the inner, sticks 1l best to suit .the length of skeins on the sticks. For that purposethe inner bearing rings 7 ,are rotatively supported on the spiders; bearings therefor 'being provided by the ends 5 ofthe inner reinforcing ribs of the spokes 5.

Suitable clips 75 on the spokes engage the outer edges of. the rings to hold themfin position. The two inner bearing rings at the center of thev double machine' shown in Fig.

1l are desirablysecured together by bolts or Aotherwise' so that `they 'will turn together r thus forming a double bearing ring. On

the binner periphery of the bearing rings a' rack or toothed segment 76 is provided.

In ernploying the worm 86 to effect theL adjust ment of the sticks .detachable securing' 1 I means to retain' the parts' inadjusted posi-' tion are not require'd'and the dse of the detachable wrench affords afcoolffhandle for the operator.

"Referring to sirable form of vstick bearlng `socketf well 85 arev not rotatingas they adapted for supporting the -innersticks. The bearing ring 7 is formed with integral socket lianges 88 open at one side to receive the sticks and a retaining cover 90 is pivotally supported on pin 91 adjacent to each socket. The cover normally is held in the position shown by a spring 93 attached toit and to the bearing ring 7 A stop projec-` tionA 94C isprovided on the cover to engage the socket iange when 1n securlng positron.

' The inner sticks 11 are similar in form to the outer sticks shown in Figs. 3 and l and to insert them in the machine the'ferrules at one end are inserted'in suitable ,apertures in one of the rings 7 and thev opposite ring is vprovided with the socket j arrangement just described. v fThe squared end v of the stick is pressed against theuppersurface of the cover 90 forcing it to yield against the action of the spring 93 to permit the entry of the stick into the socket. The inner sticks are desirably held from rotating so that the tendency of loose ends of yarn to wrap around the stick will be reduced. sockets -88 and sticks are therefore preferably squared. I.

The arrangement of the 4spring 93 isl an additional feature of thisinvention. It conp sists in an expansion spring device composed of the hooked supporting wires or Shanks 95 having the usual hooks or loops for attaching tothe cover and to the ring. The

I inner ends ofeach shank are formed with a loop 96. encircling the l other shank. Surrounding the shanks is the spiral spring'93 having contracted ends to engage 'the shank loops 96. The spring is thus confined be tween the loops so that when the shank ends are drawn apart or expanded the spring 93 will be compressed. The life of the springsz by this arrangement is prolonged for whezr I j side of the central'aXis thereof. At the op- 55 posite side is arranged a curved partition board 103 with its upper edge slightly below the level of the liquor and having its lower portion arranged, conjointly with an inclined base board 104, to form a contracted opening 105 .communicating with the space behind the partition. v'The entrance to the opening, as shown, desirably may be iiared. Thesteam distributing pipe 102 is arranged immediately behind the opening 105 andhas The openings to direct the steam toward said opening, thereby heating the liquor and dye liquid, more evenly to .distribute the dye. The circulation so effected will be seen to be in a clockwise direction as indicated by arrows in Fig. 1, the liquor moving to the rear at the bottom of the tub and at the top .passing forwardly over the partition 103 and downwardly behind it. .The pressure of the steam as it enters the bat-h will maintain this circulation'and in so doing is assisted bythe paddle action ofthe yarn enterngthebath. I 'n Absolutely to prevent the steam, under a lowered pressurefrom rising behind the partition andtendingto oppose or reverse the circulation there is provided the check valve 108;'hinged at' 109. This valve 108 in the event of an upward flow within the passage behind 'the partition, will close against a stop 110 with the result. that steam rising behind the partition will build up a pressure forcing the liquor out-through the opening.

to reestablish the proper circulation,

In Figs. 17 and 18 is shown an improved fprm of distributing pipe.102 for the ad` mission of the steam tothe bath wherein the -pipe is formed of sheet metal rolled up intocylindrical form with itsedges 115 turned inwardly to provide a longitudinal .slot 116.--

The'slot so lformed desirably may be of increasing width toward the outer ends of the pipe thereby compensating for the reducing pressure of steam toward the ends and ef-.

feet-in a more'even distribution thereof. An adjusting bolt 118 may desirably be provided at the. ends of the pipe to adjust the space between the pipe edges. l

A further feature contributing to the un.-

vestablishing a desirable circulation of the q form/distribution of the steam consists inf providing a centra-l division wall 120 in the 'ffpipe coupling 122 extending upwardly a short distance within the feed-in pipe 100.

Thereby 1s accomplished a positive mechanical division of the steam passed to the branchesof the distributing pipe 102.

The dyeis supplied t'o the bath from a suitable yreceptacle 124 .through inlet pipe 125 and a longitudinal distributing pipe 126 suitably apertured. A valve 128 isarra nged Th rou' hlv to mix the dye with the liquor as it ris a j mitted to the bath from the distributing pipe 126 there are provided a se-v 'ries of agitating sticks or paddles 130 pivo'tally hung from a horizontal bearing bar 131 parallel to the pipe 1.26 (Figs. land 15). These agitators are connected by a link 132 pivotally' secured to each and are actuated y a. rotating lever 133-fulcrumed in a bracket on the tub. One arm of levez133 is connected by link 134 to arm 4Ithe end agitator and the other of'its arms is trolled regulating valve 140 having the usual vvalve seat 141 and an operating stem 142. The valve Stem is ,connected by a small link 144 .with the stem 146 connected to a suitable spring expansion bellows 147 supported on frame 148.. Thereby the valve is operated on the contraction and expansion of the bellows to' open and close the valve. The desired movementof the bellows is effected by the action of a suitable expansible fluid 'contained within the hollow tibe 150 extending into the bathand communicating with the interior of the bellows through a pipe 152. The fluid is thus subjected lto the temperatures of the bath to be expanded to close the valve when the-heat of the bath becomes excessive.. An adjustment of the regulation is provided by a counter-balance weight 154 adjustably supported on a bar 155 ful-v erumed on'a supporting link 157 and connected to the intermediate link 144. As shown the automatically controlled valve 140 is arranged in a branch 100 around a direct valve .158. The branch is provided with v alves 159-159-to be'opened when automatic control is desired lat which time valve 158 will b e closed.

Desirable forms of improved yarn stick are shown in Figs. 10 and 21. In Fig. 10 a metallic stick is' shown formed of a rolled up, corrugated sheet of metal 160 'having its edges turned `inwardly and secured to a block '162. In Fig. 21 is shown'a modified formin which the metal is coated with a protective covering 163 of non-corrosive material of low heatl conducting value. The bearings foigtlie sticks, as shown in Fig. 21 may desirably be formed of special non-cor- 'rosive metal by providing the ferrule 36. at

\one end and the squared shoulder 23 at the A opposite'end.

unloadin of the yarn. This reverseis de sirably e ected at the same speed as the low s peed` forward. The ower is transmitted t, rough Athe gear box rom a driving pulley the drivinghaft 13 is providedon its end with a squared portion 169 to be engaged by a wrench handle for manual turning thereof should the power give out. The 'batch of yarn being dyedmay thus be saved from being unevenly dyed and spoiled in an emergency.

here illustrated in Figs. 19 and 20. It re lates to the bearing for the errule end of the sticks and the means for holding them from being. longitudinally withdrawn from the socket bearings described at the opposite ingleaf 171`is secured by suitablevrivets to the outer side of the ring to bear upon the are held in position. in Fig. 19 these holding springs 170 will yield to permit the required lengthwise withdrawal from the socket bearing. This arrangement is particularly desirable as the springs operatev by a mere pressure on .the sticks. To safeguard aga-instlateral stresses which may be excited during' the turning'of t-h'e sticks by the trip t a stationary cam 172 shown at the extrenie'opposite side of the vat from the point of introducing the steam renders it responsive to the temperature of the bath in a manner likewise having an' in- -of the dye liquoiz This el'ect obtained thereby is that upon a vCessation of the proper circulation of the liquor -(owing to reduced steam pressure or otherwise) the steam as it enters the bat-li will not be carried to the opposite wall but will rise directly. Thereforethe liquor in the vicinity of the tube will cool and will'actuate the thermostat to open the controlling valve to restablish the proper circulation.
